Abstract
Abstract The invention provides an inlay for a shoe. The inlay extends at least within the forefoot region and comprises one piece of a hard plate material of uniform thickness. The plate material is formed with a profiling provided transversely to the longitudinal direction of the sole of the shoe. The transverse profiling extends at least throughout substantially the entire forefoot region of the inlay. The profiling has a cross-section consisting of periodically repeating cross-sectional profile elements, each of the cross-sectional profile elements comprising a ridge and a recess. The plate material is a resilient plate material.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
120 words
An inlay for a shoe, comprising a plate formed of a hard, resilient plate material, said plate including forefoot and heel regions and forming inside and outside edges each extending along the forefoot and heel regions; said plate formed with profiling disposed within said forefoot region and extending transversely relative to a longitudinal direction of the inlay; said profiling having a cross-section consisting of periodically repeating profile elements, each profile element comprising a ridge and a recess, each profile element extending non-perpendicularly relative to said longitudinal direction such that said profile elements extend from said outside edge at a rearwardly open acute angle with respect to the longitudinal direction, said acute angle being in the range of 70° to 86°.
